Newsbrief: Social games giant Zynga today launched an in-game charity drive called 'Oh, What Fun!', aimed at raising money for less fortunate children in the U.S.

From November 28 and through December, players will be offered special in-app purchases across seven participating Zynga games such as Words with Friends and FarmVille, and 100 percent of the purchase price for each will go to the Marine Toys for Tots Foundation.

The not-for-profit organization authorized by the U.S. Marine Corps provides children with toys and books during the Christmas holiday season, and has been running for 65 years.
